g K w s, M is a ,v i al sectio 0i, a po -m o the v A 2 being "Shown in Fig: I Fig.- -'3 is a ,"so'me of th molds the air circplatin g a d Fig: e as a'- {similar view; illustrating Blank Referrin to fthe drawings," 2 designates 'n iipfi gli t' upport having "two Wing-like ex tnsidns' iand 4 arranged atapproxiriighanism at 'the tension 3 is formed with a horizontal bearing 5, and mounted in this bearing is the tapered journal or spindle 6 projecting from the rear of a carrier body 7. Mounted on this carrier is the sectional neck mold 8 and the twopart parison mold 9, the latter supported in the manner and operated at the intervals described in the above recited application. Also supported by the carrier so as to operate through the neck mold is the plunger 10 operated by lever 11. And, as in the former application, carrier7 is provided with a gear wheel 12 which is engaged by a rack (not here shown) for turning carrier 7 and the parts mounted thereon. Hence, when the parts are in the position shown in Figs. 1, 5 and 6, parison mold 9 is closed and is above and in register with the neck mold 8, and it is while in this position that the glass is placed in the parison mold and flows into the neck mold, as shown in Fig. 4.

The carrier 7 is ported to form a duct 13,

- one end of which communicates with a chamber 14 in an extended part 15 of the carrier, the neck mold registering with this extended part. Duct 13 extends backwardly through carrier 7 and into journal 6 where it opens through the face of the latter at 16, and when the parts are turned to blank-forming position, as in Figs. 4, 5 and 6, duct extension 16 is in register with port 17 in bearing 5 which is open to the atmosphere. There is sutficient clearance between plunger 10 and the tubular member (presently to be described) surrounding the same to permit any air, gas or products to escape from the parison and neck molds that may have become pocketed beneath the charge of glass, and which is thus prevented from forming imperfections in the blank. When carrier 7 is turned from the position of Fig. 4 to that of Fig. 1, duct'extension 16 registers with pipe 18 for admitting air to the blank, as will presently appear, at such time port 17 to the atmosphere being blanked.

19 is a tubular member which is operative in cavity 14 of the carrier extension 15, and which projects into the neck mold 8, with its extremity forming a part of the bottom closure of the mold cavity when the glass is entered in the parison and neck molds to form blank B, as shown in Fig. 4. At this time the extremity of plunger 10 is flush with the end of member 19, but there is sufficient clearance between the plunger and said member to permit air to escape thereinto from the molds and from thence through ports 20 to duct 13. The tubular member is held normally projected by spring 21, and is adapted to work through fixed bushing 22 provided with the wedge-like teeth 23, while secured to the extremity of member 19 is head 24: provided with the wedge-like teeth 25 complementary with teeth 23, so that when head 21 is turned by handle 26, the tubular member-is retracted as shown in Figs. 5, 6 and 7, fixed stop 27 limiting the movement so that the parts are held in separated position as in Fig. 7 when the handle is fully turned. Before the plunger 10 is thrust into the blank by its lever--11, the tubular member is moved away frorn=the glass, as shown in Fig. 5, so that when the plunger is projected as in Fig.-6, the extreme edge of the blank is neither chilled nor'its movement retarded, the glass being'free to turn inwardly slightly or follow the plunger and form the blank with a preferably rounded neck extremity.

In my former application, one pipe is shown for supplying air for blowing'and also for operating a cylinder mechanism which actuates the parison -mold. In the present adaptation, the air for blowing is supplied through pipe 18, and air for operating the mold actuating mechanism is supplied through a separate and distinct pipe 28, the carrier 7 and its spindle 6 being ported at 29 to pass the air for this purpose, the mold actuating mechanism operating as described in my above mentioned aphcatlon.

After the blank has been formed and carrier 7 turned to move the blank from upright position, as:in Fig. 4, to depending position, as in Fig. 1, the parisonmold sections separate and are replaced by a blow mold 30. The blank 13 at such time is shorter than the depth of the blow mold, and it is desirable to elongate it by relatively low air pressure before finally blowing it. The low pressure air, together with the tendency of'the blank-to elongate bygravity, operate to change the blank from the shape shown in full lines in Fig. 6 and in dotted lines in Fig. 1 to that illustrated by full lines in Fig. 1, when the blank reaches nearly to the bottom of the blow mold. To admit air for this elongation, a pipe 31 is in communication with pipe 18 through a three-way valve 32, so-that as soon as carrier 7 and its spindle 6 have been turned to place the blank in suspended position, as from that shown in Fig. 4 to that of Fig. 1, duct extension 16 registers with pipe 18, and a limited amount of air is admitted into the blank cavity, thereby at once and automatically starting the elongation of the blank, Assoon as the blank has been sufficiently stretched the operator closes the blow mold (said mold having been open when raised to blowing position), and the three-way valve is turned to admit the full air pressure from a second pipe 33 for blowing the blank into a completed bottle.

A needle or like graduating valve 34 is placed in pipe 31 so that a minute adjustmentmay be made for obtaining the exact volume of air requisite for elongating the blank. The normal position of the three- V and 31.

tion indicated in dotted lines in Fig. l3,

thereby establishing full communication between pipes 18 and 35 :and admitting the full blast of air. The extreme position of valve 32 may be determined by. a stop pin 37 which is engaged by shoulders on the valve, as shown in-Fig. 9. I

Instead of using a single blow mold as contemplated in the adaptation. shown in my above recited application, I have here arranged for the use of a plurality of blow molds,so that the operation of the machine need not be delayed when removing a'blown bottle; also by using several molds they are prevented from becoming too highly heated. In the arrangement here proposed, table 40 is mounted to revolve on a vertical axis, beingv preferably provided with a ball bearing 41, andis provided with three mold positions so that. by turning the table one after the other of the blow molds30 may be placed into vertical line with the neck mold.

The blow molds are loosely seated on table 46 in or above openings 42, the latter being open through the edge-of the table, as indicated at 43. Operating through opening 43 is arm 44 provided with a lifting head 45 which is normally beneath table 40, but which is raised when the mold is to be lifted, the raised portion of the headentering a cavity in the frnold bottom, as illus trated in Fig. l, and at the rightha'nd side of Fig. 2, thus centering the mold on the lifting device and moving it into accurate register with the neck mold.- The lifting arm 44 is carried by a slide 46. Piston 47 is connected to this arm and extends from cylinder 48 at the base of the machine, air for operating the piston being controlled by a treadle-actuated valve 49. Table 40 may be turned by hand, and the spring-actuated locking rod 50 engages holes 51 in table 40 for holding it with one or another of the molds in operative position. The locking rod may be conveniently released by a foot lever 52.
